freshwater fish biodiversity is a precious natural asset in terms of economic, cultural and scientific interest. and yet, the inland freshwater ecosystem in malaysia is declining at a far greater rate than terrestrial ecosystems in the tropics. what happened, and what is being done to address the crisis? this paper extracts findings from the latest literature and explores overarching issues per...

a systematic parasitological examination was carried out on 266 freshwater fish speci-mens, belonging to 11 species, from northwest of iran during the period from summer 2001 to summer 2002. twelve parasite species including diplostomum spathaceum, al-locreadium isoporum, ligula intestinalis, digrama sp., caryophylleus laticeps, rhabdocona hellichi, eustrongylides excisus, argulus foliaceus, la...

A virus causing a vacuolating encephalopathy and retinopathy in juvenile sea bass, Dicentrarchus labrax, was isolated from brain tissue in a fish cell line (SSN-1) derived from striped snakehead, Channa striatus. The isometric, non-enveloped, 30 nm diameter virus particles were resistant to pH 2-9 and heating at 56 degrees C for 30 min. Infectious particles had a buoyant density of approximatel...

Kondisi lingkungan diduga mempengaruhi kadar albumin pada ikan Gabus, dimana kandungan ini sangat baik untuk menjaga kesehatan karena mengandung asam lemak esensial, mineral zink, dan kolagen. Penelitian bertujuan mengetahui Mengetahui bagaimana hubungan habitat ukuran konsentrasi albumen Gabus (Channa striata). merupakan jenis penelitian kuantitatif, menggunakan metode explanatory research den...

Huge amounts of evaporation and precipitation exist over the ocean and play an important role in the global climate system. Therefore, evaluation of freshwater flux is critical for understanding the mechanism of global climate change. Recently we can use three kinds of global freshwater flux products such as in situ data, satellite data and reanalysis data. Although various studies were carried...

Here we present a complete list of all valid species-group taxa of freshwater gastropods reported from Miocene and Pliocene deposits in Europe. The last comparable work dates back to the 1920s and covered about 1,600 names. The extensive literature research underlying the present work revealed considerable changes in the taxonomic and systematic frameworks of Neogene freshwater gastropods and y...

Channidae Family is a predatory fish in Central Kalimantan. This fish also possesses high albumin and complete amino acid content that useful for health, particularly in wound healing. Channidae Family includes Gabus (Channa striatus), Toman (Channa micropeltes), Kerandang (Channa pleurophthalmus), and Mihau (Channa maculata). However, the phylogenetic relationship between these snakehead fishe...

The January 2011 Special Issue is the first major compilation of studies on systematic conservation planning in fresh waters (Turak & Linke, 2011). The papers in this Special Issue consolidate freshwater conservation planning as a field within both conservation science and freshwater ecology. This progress is largely a result of key advances in both disciplines (Linke, Turak & Nel, 2011). Many ...
